Firefox Support Forum

The 125.0.2 update broke Amazon Prime Video. Firefox refuses to play ANY video, causes website to return a "That shouldn't have happened" error page. Prime Video plays just fine on Safari 16.6.1, macOS 11.7.10. Amazon says just to use Safari, but I want Firefox to work right.

I did an Upgrade to a version of Firefox that would bypass those "Your Browser Is Not Supported" messages that apparently come from "Cloud-flare." I figured [naievely!] that my addons would "port" to the upgrade. They didn't. Is there any way [e.g., a putative backup file, perhaps] that would allow this?

Thanks in advance...!

Hello. In the last few days when I visit my Shopify website, the pricing on my products is not visible. This is only for me, nobody else has this issue. I do not have this issue on Safari, or on Firefox when I open a private browsing window. It is something to do with Firefox, but I don't want to have to open a private window every time I go to my store. Is there a solution? This has only been happening for the last few days. Thanks

Hello Good People,

I noticed that the snap version of Firefox had a lag issue when typing into input field. For example, when composing an email and wanting to use backspace to quickly delete a misspelled word, then backspace works slowly, stuttering and jittering. If I hold down a key in the input field it also lays the character down in a stuttery, slow way.

I tried reinstalling the system and that solved the issue. But it has returned again. Maybe it was an update. I also installed WINE and waybridge to get some windows plugins to work on my DAW. I don't know if that has affected it.

I also tried removing the snap version and installing firefox using the terminal but the problem persisted.

It's an annoying problem. Any advice appreciated.

Just recently Firefox seems to have its downloads capped at 15-16 meg speedtests show the full 1Gig speed OPERA AND EDGE both download at the full 999 megs but firefox has recently stopped downloading any faster then 19 meg

what in firefox could be causing this its not happening in any other browser.

I am watching a Twitch video on Firefox. When I open a new Firefox tab and drag it to another monitor, the Twitch video skips forwards about a minute.

I also occasionally notice skips or pauses when I switch from one tab in the same window back to the Twitch playing tab.

Is there any way I could fix these problems?

This happens on other websites as well: https://www.exploit-db.com/

Can you help?

Picture-in-picture since recent YouTube update keeps closing. Is there way i could configure in about:config to never close and always stay open even if page refreshes and have it move the video play back always to the Picture-in-picture window ? If not could this be made a feature in a future update ?

YouTube especially been annoying to Firefox users, cos it keeps refreshing the whole page breaking stuff every time it plays the video, as well have issues with looping videos even tho they are already fully buffered, making entire YouTube experience as frustrating as possible as encouragement to switch to chrome, which i refuse for obvious reasons.

Anything i can do on my end ? If tested if this happens in incognito mode as well with all extensions disabled in private windows, no change of behavior.

Btw this happens on the new YouTube interface with no way to get back to the old interface, cos it keeps the annoying features of the old interface even if you try to re position stuff using hacky ways like extensions that do so, which of course break stuff even further. I just want Picture-in-picture to remain open, and to play current video in picture-in-picture that is playing automatically.

Btw the Picture-in-picture experience with chrome or chrome based browsers is absolutely horrible, giving me even more reasons to stay on Firefox besides privacy related issues and other issues.

Hello. I have a pretty big sprite image i am trying to display on my web page but mozzila wont display it. The sprite is 78016px by 1000px and im cropping it to be 736px by 1000px. Sprite is made out of a png sequence that was made in 3d software, now the thing is when i put in the non rendered verson of images(3D viewport colors) which windows labels as 8bit (maybe because of less colors) it gets displayed, but when i put the rendered version which windows labels as 32bit image it wont get displayed on Mozilla. It gets displayed on Chrome and Edge without any problems. The only difference beetween the images is that the rendered version has a transparent background behind the subject...they are the same sized sprite. I will drop the first frames of the sprite in the images section so you can get a better idea. Also all of the code and images is stored locally.

I am on a brand-new machine and having trouble setting up the Firefox browser.

When I click on a link it opens in a new window with all the tabs ready opened.

How do I open a tab without opening a new window?

Also, how do I set Yahoo.com as my default search engine?

Thank you for sharing your wisdom

Hello, When i create a new tab (cntrl + T) I can no longer just start typing and have that be a google search. Now I need to manually click in the search bar. Is there a way to enable it so creating a new tab automatically puts the text into the search bar field?

Not sure why this stopped working, maybe a recent update. Thanks for your help.
